header() refresh vs location

All, I have done a number of searches. I have read the online documentation and user supplied comments. I recently ran into problem using: -some code here to create session and set variables- header('Location: index.php'); where the sessions would sometimes get "lost", they wouldn't make it to the index.php page. A print_r on $_SESSION would display an empty array. And yes the sessions are getting set properly. The same code works on three different servers, with no modifications. So a friend recommended using: header ("Refresh: 0; url=index.php"); I haven't seen documentation for "refresh" in the header function. Is there any reason to use one in lieu of the other? Any comments on 'refresh'? As I said, I've looked at the online documentation: this page: http://us4.php.net/manual/en/function.header.php doesn't have the word "refresh" on it. this page: http://www.w3.org/Protocols/rfc2616/rfc2616 doesn't have the word "refresh" on it. this page: http://us4.php.net/manual/en/function.headers-sent.php does have the word "refresh" but it's not relevant. Thanks in advance.
